Commercial Solutions for Classified

High-security and classified mobility, without the guesswork.

CSfC lets you carry classified data on commercial phones and tablets — and the same layered architecture underpins high-security deployments below that threshold. The framework is public; the hard part is turning hundreds of pages of requirements into a build your team can actually field. That translation is what we do.

What We Do

Four ways we shorten the distance to a fielded solution.

Every engagement comes back to the same problem: the requirements are public, but nobody hands you the build. We close that gap.

01

Simplify the Architecture

Dual-layer encryption, VPN tunneling, and Data-at-Rest frameworks broken down into straightforward blueprints for modern end-user devices — diagrams your engineers can build from, not paragraphs they have to decode.

Device Specific Deployments

Guidance tailored to the endpoint in your hand: Android and iOS smartphones and rugged tablets operating in tactical or enterprise environments. Different form factors, different constraints, different answers.

03

Bridge theory and practice

Compliance standards — NIAP Protection Profiles, STIG policies, Capability Package requirements — translated into practical steps that engineers, integrators, and mission planners can execute without a legal reading.

04

Accelerate fielding timelines

The whole point of CSfC is leveraging commercial off-the-shelf technology to reach secure classified mobility in months rather than years. We help teams take that path instead of rediscovering it.

The Architecture

Two independent layers. One clear path to the enclave.

CSfC protects classified data by wrapping it in two nested encryption tunnels built from different products, so a flaw in one layer never exposes the data underneath. Here is that path, end to end.

Inner layer

Independence is the whole point

The two layers must come from genuinely different implementations. Repeating a vendor collapses two layers into one shared failure mode — and the design will not register.

Data at rest is its own problem

Protecting the tunnel says nothing about the powered-off device. DAR solutions layer their own encryption on the endpoint, with a separate Capability Package and separate design decisions.

Registration is not an afterthought

Solutions are registered with NSA against a compliance checklist. Designing with that checklist in view from day one is the difference between a build and a rebuild.

Android in CSfC

Two Android paths. They are not interchangeable.

Android dominates CSfC mobile deployments, but "Android" is not one decision. Google and Samsung take measurably different approaches to the pieces CSfC actually cares about — certification cadence, the Data-at-Rest story, and how much of the stack comes from a single vendor. Picking the wrong one costs you a redesign, not a settings change.

Google Pixel

First-party silicon, the fastest Common Criteria cadence in Android, and a clean AOSP baseline — with a Data-at-Rest gap you have to fill yourself.

  • Certified against PP_MDF v3.3 on current Android
  • Titan M2 and Tensor crypto under FIPS validation
  • DISA STIGs published for current releases

Samsung Galaxy

Knox brings something Google does not: an NSA-approved inner encryption layer built into the platform, plus hardware purpose-built for the tactical edge.

  • Knox DualDAR — both DAR layers from one platform
  • Knox File Encryption approved by NSA for the DAR CP
  • Tactical Edition hardware for field deployments

A certified device is not a compliant solution

Both platforms carry impressive certifications. Neither is CSfC-compliant on its own. The device is one component in a registered architecture that also includes your VPN layers, gateways, management infrastructure, and a compliance checklist. Start from the Capability Package, not from the datasheet.

Capability Package Tracker

What's current, at a glance.

Capability Packages move. Designing against a superseded version is one of the most expensive mistakes a program can make, so we keep the current state visible.

Capability Package Version Published Covers
Mobile AccessMA v2.8.0 27 Mar 2026 Remote access for mobile end user devices
Multi-Site ConnectivityMSC v1.3.0 27 Mar 2026 Linking enclaves across untrusted networks
Campus WLANCWLAN v3.2.0 27 Mar 2026 Classified Wi-Fi inside a controlled campus
Data-at-RestDAR v5.1.0 Mar 2026 Layered encryption on the storage itself
TacticalTACT v1.0.0 1 Jul 2024 Deployments at the tactical edge
Current as of August 2026. The March 2026 releases introduce objective CNSA 2.0 post-quantum requirements — worth reading before you lock a design. Always confirm against nsa.gov before building.
Who We Help

Built for the people who have to make it work.

Security engineers

Standing up the tunnels, the gateways, and the device configuration — and answering for every one of them.

Systems integrators

Assembling components from the approved list into something that registers the first time.

Mission planners

Deciding what secure mobility actually enables at the edge, and what it costs to get there.

Program offices

Scoping timelines and budgets against a framework that rewards getting the design right early.

About

Demystifying secure mobility.

ApexCSFC exists for a simple reason: the frameworks that govern secure mobility are publicly documented, rigorously specified, and genuinely difficult to act on. We deliver simple, actionable breakdowns across both halves of the problem — high security solutions built on NIAP-validated devices, DISA STIGs and hardened UEM baselines for sensitive and CUI work, and full CSfC architectures for data that is classified — on smartphones and tablets, so teams spend their time building rather than interpreting.

Placeholder — replace this block

Your background goes here. A short paragraph on who is behind ApexCSFC: years in the space, programs supported, relevant credentials or clearances you're willing to state publicly.

This is the section that converts a curious visitor into an inquiry, so it is worth writing yourself. Two or three paragraphs, plus a headshot, is the right size. Send me the details and I'll fold them in.

Have a mobility problem worth solving?

Whether you're scoping a first CSfC deployment or untangling a design that stalled, start with a conversation. No obligation, no procurement pressure.
